MOLD FOR MAKING SADDLE-PADS.

SPECIFICATION forming part of Letters Patent No. 683,605, dated October 1, 1901.

Application filed December 11, 1900- Serial No. 39,476. (No model.) I

To aZZ whom it may concern.-

Be it known that we, JONATHAN A; HUNT and J ENSIGN WEATHERWAX, citizens of the United States, residing at Westboro, in the county of Worcester and State of Massachusetts, have jointly invented certain new and useful Improvements in Molds for Making Saddle-Pads, of which the following is a specification.

Our invention relates to molds for making yielding pads or cushions designed particularly to be used in saddles for bicycles, tricycles, &c., to be inclosed between the top and bottom covering of the saddle.

Diflferent materials have been used for the pads, as hair, felt, sea-moss, &c. In the case of hair pads the pads have been cut or stamped out by dies or otherwise from sheets of what is termed interlaced hair, and in cutting up the sheets of hair for the pads there is considerable waste and the edges of the pads are left square and sharp-cornered and have to be rounded before the pad is used, ordinarily by hand, to conform to the shape of the completed saddle.

The object of our invention is to improve upon the ordinary manner of and means for making cushions or pads for saddles, 850., above described, and to do away with any waste of the material and any necessity of rounding the edges of the pad, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a top or plan View of a mold which is used in making our pad. Fig. 2 is a bottom view of the mold shown in Fig. 1. Fig. 3 is a section on line 2 2,Fig. 1, looking in the direction of arrow a, same figure. Fig. 4 shows the pressure-plate removed. Fig. 5 is a plan view of the finished hair pad after it is removed from the mold; and Fig. 6 is an edge view of the hair pad shown in Fig. 5, looking in the di rection of arrow 1), same figure.

In the accompanying drawings, 1 is a mold or form, preferably made of a single wall of copper and having the shape of its interior surface corresponding to the desired shape of the pad to be made.

The mold 1 has in this instance its bottom perforated or provided with openings 0, which are all preferably of uniform size and are madetapering, with the larger end on the out side of the mold, as shown in Fig. 3.

The mold 1 has a central rib or division d, dividing the mold into two equal parts e e, the bottoms of which are rounded or curved at the edges, as shown in Fig. 3. The bottom-of the smaller end f of the mold 1 is also rounded or curved at the edges to conform to the curvature of the parts e e.

In connection with the mold or form 1 is used a covering-plate 2, w ich is in this instance perforated or provided with openings g, preferably all of uniform size and corresponding to the size of the openings 0 in the bottom of the mold 1. The openings g are made tapering, with the larger end on the upper side of the covering-plate 2 when it is in position in mold 1, as shown in Fig. 3.

The covering-plate 2 fits loosely within the mold 1 and is held therein preferably by means of two pins 3 and 4, one of which, as 3, extends through transverse openings h in the two sides of the mold 1 and the central rib cl at the rear end of the mold and the other, as 4., through transverse openingsi in the two sides of the mold 1 at the forward reduced end of the mold, as shown.

We will now describe the method of making hair cushions or pads in using the mold or form 1 and covering-plate 2, above described. l/Ve first take a certain amount of hair, which is loose or in the condition in which it is marketed for ordinary use in mattresses, &c., and put it into the mold 1 and spread it around, so that it will be of substantially uniform thickness in the bottomof the mold. We then place the covering-plate 2 in the mold on top of the hair and press said plate down to compress the hair until the top of the plate is below the transverse openings h and 7:. Then we insert the holding-pins 3 and a to hold the plate, as shown in Fig. 3. The mold 1 is then placed in a steam-chamber for a short time, and the steam passes through the perforations c in the bottom of the mold 1 and the perforations g in the covering-plate 2 and circulates through the hair in the mold and acts to compact and set the individual hairs into fixed shape. The mold is removed from the steam-chamber and placed in a heated or drying chamber for a certain time,

where the hot air circulates through the hair in the mold, which is then removed and the pins 3 and i drawn out and the covering-plate 2 removed, and then the finished pad 5 (shown in Figs. 5 and 6) is removed and is ready for use to be placed between the upperand lower covering of the saddle proper without any further manipulation or handling.

The advantages of our improvements will be readily appreciated by those skilled in the art. There is no waste of hair in making the pads, as only the exact amount of loose hair is put in the mold which is required to make the desired thickness of the pad. There is no necessity of rounding the edges of the pad after it is made, for the rounding of the edges is done in the molding operation.

It will be understood that the details of construction of the mold and perforated plate shown in the drawings may be varied if desired.

We prefer to have the perforations in the bottom of the mold and also the perforations in the covering-plate, so that the steam 'or hotair can pass up through said perforations, but this is not essential.

The shape and size of the mold may be varied as desired, according to the desired shape and size of the cushion or pad to be made, and we do not limit ourinvention-to cushions or pads for saddles, as the cushions or pads may be used for other purposes, if desired.

We have described the use of hairin making our pads, and we prefer to use hair, as it makes a yielding and durable pad, and the action of the steam on the loose hair after it' is compressed in the mold sets and compacts the individual strands of hair in a most satisfactory manner, so that the completed pad is of uniform yielding capacity; but we may use other materials instead of hair, as felt or sea-moss, &c.

It will be noticed that the holes in the mold and covering-plate have their inner ends flush or in the plane of the surfaces of the mold and covering-plate and are made tapering, with the larger end on the outside of the mold and covering-plate, for the reason that the mold and plate being formed of cast metal the parts draw from the sand more readily after casting, and, moreover, by such formation of holes a more ready diffusion of the steam throughout the pad in a highly-heated condition is secured.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A mold for making cushions or pads, comprising a form or receptacle made of a single containing-wall suitably shaped to receive the material, said form having perforations therein for the passage of steam to circulate through the material contained in the form, and a plate to extend entirely within the form to cover thematerial said coveringplate being also provided with perforations, and means for holding said plate in the form to compress the material.

2. A mold for making cushions or pads, comprising a form suitably shaped to receive the material, said form having perforations therein for the passage of steam to circulate through the material contained in the form, the inner ends of the perforations being flush or in the plane of the surface of the mold, said form being also provided with transverse openings and a covering-plate to extend entirely within the form, and means for holding said plate in the form to compress the material, said means comprising a pin extending through the transverse openings and above the covering-plate.

3. A mold for making cushions or pads,

comprising a form suitably shaped to receive the material and having perforations therein and a perforated covering-plate to extend and be contained within the form, said perfora tions permitting the passage of steam to circulate through the material and having their inner. ends flush or in the plane of the surfaces of the mold and coveringplate, and cross-pins extended through the walls of the form, and above the covering-plate to hold the latter in place while the material is being subjected to the action of steam or the like.

4. A mold for making cushions or pads, comprising a form suitably shaped and provided with perforations, said form having a central rib or division dividing the mold into two parts, a covering-plate adapted to fit within said form and also provided with perforations, the hair or other material adapted to be contained within said form to overlie the perforations in the form and coveringplate, whereby steam may be permitted to pass through the perforations and circulate through the hair or other material and means for holding the covering -plate within the form.

5. In a mold for makingpads for saddles, &c., the combination with the body part or form, suitably shaped, and having tapering openings or perforations in its bottom, with the larger ends on the outside, said form also having a central rib dividing the mold into two equal parts, of a covering-plate to extend and be contained within the form, and having tapering openings or perforations therein, with the larger ends on the top side of the plate, and means for holding the plate in the form, substantially as shown and described.
